The compressor had previously established currents while
running and then all three phases of current were lost. Design:
Less than 10% RLA, trip in 2.64 seconds. This diagnostic will
preclude the Phase Loss Diagnostic and the Transition Complete
Input Opened Diagnostic from being called out. To prevent this
diagnostic from occurring with the intended disconnect of main
power, the minimum time to trip must be greater than the
guaranteed reset time of the Starter module. Note: This
diagnostic prevents nuisance latching diagnostics due to a
momentary power loss - It does not protect motor/compressor
from uncontrolled power reapplication. See Momentary Power
Loss Diagnostic for this protection. This diagnostic is not active
during the start mode before the transition complete input is
proven. Thus a random power loss during a start would result in
either a "Starter Fault Type 3" or a "Starter Did Not Transition"
latching diagnostic.
